Cut the salami into slices. Grate the cheese.
Mix warm water with yeast. Add sugar, mix well and leave for 5 minutes. Sift the flour, add salt and honey and knead the dough. Knead the dough by hand for 2-3 minutes, adding flour if necessary.
Place the dough in a container greased with a thin layer of oil, cover with a towel and place in a warm place for 60 minutes. Set aside a quarter of the finished dough to form the sides of the cake.
Divide the remaining dough into 5 equal parts and roll each into a thin layer. Cut a round blank from each layer, focusing on the diameter of the mold used. Bake each base in an oven preheated to 200°C for 3-5 minutes.
Roll out the remaining dough into a rectangular layer, cut into two parts and line the sides with dough. Trim off the excess dough with an allowance for finishing the edges.
Place the first cake layer on the bottom of the pan and brush it with a tablespoon of sauce. Spread some pepperoni and top with a little cheese. Alternate layers until the mold is filled. Fold the edges of the dough over. Bake at 200°C for 25-40 minutes.
